Embodiment 1

[0017] Example 1 Cutting propagation of Dendrocalamus latiflora

[0018] At the beginning of April, the cutting propagation of the green bamboo was carried out in the nursery of Yucheng District, Ya'an City, the experimental site of Sichuan Agricultural University. First, choose the hilly yellow soil with good light conditions, convenient irrigation and drainage, convenient transportation, and loose and fertile soil as the nursery. Deep digging and then leveling, through two turns and two rakes, to achieve the requirements of flatness, thinness and softness, and pick up the roots of weeds. Apply 37500kg~45000kg of decomposed farmyard manure per hectare, and use KMn0 4 Use carbendazim solution to disinfect the soil and clean up the ground to facilitate drainage. Open a seedling ditch on the flat border with a depth of 15cm and a width of 20cm.

Embodiment 2

[0069] Example 2 Propagation by cuttings of green bamboo and sweet dragon bamboo branches

[0070] The basic process of cuttings of green bamboo and sweet dragon bamboo is the same as in Example 1.

[0071] Two rooting promoters of IBA and ABT were selected for the main branch of the 2a belt on the 2a mother plant, and four concentrations of 100ppm, 200ppm, 1000ppm and 2000ppm were designed respectively, and the comparison was made with clear water. There were 9 treatments in total. 100ppm, 200ppm soaked for 10h, 1000ppm and 2000ppm soaked for 10s, completely random block arrangement, repeated three times, each block cut 80 bamboo branches.

[0072] The cutting time was in early April, and the routine field management after cutting was also the same as in Example 1.

Abstract

The invention discloses a cuttage propagation method for clumping bamboos, comprising the following steps: selecting a seedling culture nursery land, and flattening the nursery land; dipping a bigslip into 100-200ppm of an IBA (iso butyl alcohol) solution or an ABT solution, or dipping in 1000-2000ppm of the IBA solution or the ABT solution; inserting the bigslip processed by a hormone into a seedling culture ditch, covering with soil and tramping; and spraying water and covering with grass. With the method, the cottage survival rate of dendrocalamus affinis, big allusion bamboo, Dendrocalamus latiflorus or Dendrocalamus brandisii is improved by above 35%, and the method has an important meaning for the industrial mass production of the bamboo seedlings and promotion afforestation.

Description

Technical field [0001] The invention belongs to the field of plant seedling cultivation and cultivation, and particularly relates to a cutting propagation method of clump bamboo. Background technique [0002] Commonly used techniques for raising seedlings of clump bamboo include burying stems, burying single nodes, burying double nodes, burying three nodes, burying seedlings and cutting seedlings. [0003] Cutting seedling breeding materials have low cost, fast reproduction speed, short seedling time, simple seedling raising technology; convenient introduction and transportation; suitable for large-area afforestation and seedling cultivation; mother bamboo and branches are easy to obtain, and the utilization rate is high, so it is one of the methods of clump bamboo afforestation A more ideal method. However, the cuttings have poor ability to adapt to the environment before they take root, require fine management, are not easy to take root, and have a low survival rate, failing to ...
